python 发邮件写例子

#! /usr/bin/env python 
from email import encoders
from email.header import Header
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr
import smtplib
import sys
from email.mime.text import MIMEText
mailto_list=['[email protected]']          
mail_host="smtp.sohu.com"  #邮件服务器的域名 如：smtp.sohu.com pop3.sohu.com等
mail_post="25"         
mail_user="xxx"            #邮件服务用户名              
mail_pass="xxx"         #和邮件服务登录的密码                   
mail_postfix="sohu.com"                    
def send_mail(to_list,sub,content):
    me="hello"+"<"+mail_user+"@"+mail_postfix+">"
    msg = MIMEText(content,_subtype='plain')
    msg['Subject'] = sub
    msg['From'] = me
    msg['To'] = ";".join(to_list)               
    try:
        server = smtplib.SMTP()
        server.connect(mail_host,mail_post)                           
        server.login(mail_user,mail_pass)              
        server.sendmail(me, to_list, msg.as_string())
        server.close()
        return True
    except Exception, e:
        print str(e)
        return False
#for i in range(5):                            
    #if send_mail(mailto_list,"hello","haha!"): 
        #print "done!"
    #else:
        #print "failed!"
if __name__=="__main__":
    to_list = sys.argv[1]
    sub = sys.argv[2]
    content = sys.argv[3]
    #print to_list
    #print sub
    #print content
    send_mail(to_list,sub,content)

运行命令：python sendmail.py [email protected] hi hello

通过cmd传三个参数

python程序外部参数通过sys.argv传入，sys.argv为list。
sys.argv第一项为程序文件的名称，后面的依次为参数列表

参数之间用空格隔开

sys.argv这个参数就好比我们java中的main函数中经常看到的argv[]
